To all whomit may concern." 4

Be it known that I, MIRKC- HIKEB, a S1ll) ject of the Emperor of Austriafiungary, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Combined Window Sashes and Screens, of which the followin is 'a full, clear, and'exact description, re erence being had to the accompanying drawings, forming a part hereof.

My invention has relation to improve ments in combined window sashes and screens; and it consists in the novel details of construction more fully set- -forth in the specification and pointed out in the' claim.

In the drawings, Figure 1 is a front elevation ofsa window frame, with" parts broken away, showing my invention applied thereto; Fig. 2 is, a vertical crosssection on the line 22 of Fig. I; Fig. 3 is an elevation of thewindingdrum showing the web nnrolled therefrom so as to disclose the manner of securing the inner. end of the Web to the drum; Fig. l is an inner end View of one of the drum-heads or cups; and Fig. 5 is a detail showing the loot-tom rail of the sash broken to show the manner of mounting the locking bolt.

The object of my invention is to pro vide, a flexible Wife-111E311 sheet or web adapted to be wound about a drum in a compartment below the window frame, one end of the sheet being connected to the bottom rail of the sash, whereby, as the sash is raised the sheet will be pulled with it and thus unwound from the drum, and thereby serve as a fly-screen. A closin of the sash w ll causean automatlc wint iug or wrapping of the sheet about the drum, so that when the sash is fully closed, the screen will disapnear wholly Within the compartment or casing in which the drum is located.

The invention, though here illustrated in connection with the lower window-sash may, with equal. propriety be used with the upper sash, the drum compartment in that case beinglocated at the top of the window frame instead of at the bottom, as will be clearly obvious from a detaileddescription oi the invention which is as follows Referring to the drawings, F representswhich is removable: Depending from. the roof of the casing C are bracketsor hangers 2, 2, for the support of the cylindrical axle-bar 3, the barhaving square ends supported in the brackets and thus prevented" connected by longitudinal braces or bars 7 thus forming a skeleton drum the com ponent parts of which rotate as a unit about the axle 3. One of the hubs 5 is provided; with an opening 0' which me he brought" in register with a correspon ln'g opening in the axle 3, for the reception of a pin 0:, whereby the drum may be held against rotation. and thus prevent unwinding of the springs when occasion arises'to replace-e Worn out sheet or web 8 constituting the screen. I

The inner end of the screen-web is secured tOuOIlQ of the bars F and the wehwrapped about the drum: a suitable number of times, the outer end of the web being passed through a slot 5: inthe sill A and secured on i the outside of the sill to an angle-bare 9 the horizontal leg of which rests on the sill for a closed position of the sash S. The length of the vertical leg of the angle-member 9 is equal to that of the bottom rail of the sash, the ends of said leg traveling in the samegrooves h with the sides of the sash,

the horizontal leg being cut off so as to terminate just wit in the frame F (Fig. 1).

To the inner face of the vertical leg of the angle-bar 9 are pivoted latches l0, l0, swinging in vertical. planes parallel to the sash, and when swung out the hooked terminals of the latches engage pins 11, 11, on the sash rail, thus coupling the web 8 to the sash. Each latch is provided with a lip 12 bentoutwardly from an arm 13 formed on the latch, the lip 12 being adapted to reston the edge of the vertical leg of the member 9 and thus arrest the latch when. the latter is swung to its depressed position and cm of engagement with the keeper or pin ll. When thus depressed the latch is concealed from View, nothing-showing except the edge of the lip 12 resting on the memher 9. At

ill)

--sired position. By turning the knob 14 in the center of ,the bottom rail of the sash'i s a rotatable button or knob 14 tothe stud 14 of which is secured a slottedarm l5traversed by \a pin 16' at the inner end of; a

locking-bar or bolt 17 operating in apassage-way (Z leading from a-cavity D formed in the sash rail for the''- housing of the arm 15. The outer end of the bolt cooperates with the sockets m on the side of the frame F for holding/the window open at any deproper direction the bolt '17 may be moved so as to lock or release the sash. The sashlock however is well known and forms no part of the present invention. Features shown but not referred to are well-understood-in theart and require *no'description in the present connection. The operation -'may-- be described as follows By swinging the latches" 10 up so as to engage their keepers 11- on the sash 'rail,

and raising the sash, it isobvious that the web -8 now anchored to the sash will be pulled up with it and proportionately un- (see dotted position Fi .1) thus disconnecting the screen from t e sash. The latter may then be raised or lowered without disturbing the screen. Should it be desirable to replace a worn screen by a' new one, the.

old screen is detached-from the sash and pulled'out through the slot 8 until the drum is fully unwound. The wall 1 is removed and a pin a is inserted through the registering opening in the hub of one of the drumheads. and, t e axle (Fig. 3) whereby the springs 6, 6, (now'under tension) are pro vented from turning the drum. The old screen-web is then detached from the bar :7 and pulled entirely out through the slot 8. The inner end of the new web is then inserted from the outside through the slot 3 fastened to the'druni, the pine pulled out and the springs allowed to .wind the new web on the drum, the member 9 carried by the outer end thereof settling on the sill A, after which connection thereof with the sash, is made by the latches 10. The new web being in place, the wall 1 is restored thus covering the casing O.

Having described my invention, what I claim is IA. movable screen provided with a terminal angle-bar operating in front of, and in conjunction with a sash-rail, a latch pivoted to a leg of the angle-bar and operating in the space between said leg and rail, and adapted to be coupled to the rail, the latch being provided with an outwardly deflected lip to engage the edge of the leg of the angle-bar for a-released position of the latch.

In testimony whereof I aflix my signature. in presence of two Witnesses.
